Here’s some pics of a conventional sectional core radiator for a Komatsu shovel we rebuilt. The radiator is comprised of a low-temp half & a high-temp half which is basically two radiators to make up the complete assembly. The cores of the radiator are conventional type with flat continued fins in an MB (mechanically bonded) configuration. We completely disassembled both radiator halves, gave them both a rod & repair & final pressure test to ensure there were zero leaks after final assembly.
